Joey Hess 7189dfd77d git-annex (5.20131127) unstable; urgency=low
* webapp: Detect when upgrades are available, and upgrade if the user
    desires.
    (Only when git-annex is installed using the prebuilt binaries
    from git-annex upstream, not from eg Debian.)
  * assistant: Detect when the git-annex binary is modified or replaced,
    and either prompt the user to restart the program, or automatically
    restart it.
  * annex.autoupgrade configures both the above upgrade behaviors.
  * Added support for quvi 0.9. Slightly suboptimal due to limitations in its
    interface compared with the old version.
  * Bug fix: annex.version did not get set on automatic upgrade to v5 direct
    mode repo, so the upgrade was performed repeatedly, slowing commands down.
  * webapp: Fix bug that broke switching between local repositories
    that use the new guarded direct mode.
  * Android: Fix stripping of the git-annex binary.
  * Android: Make terminal app show git-annex version number.
  * Android: Re-enable XMPP support.
  * reinject: Allow to be used in direct mode.
  * Futher improvements to git repo repair. Has now been tested in tens
    of thousands of intentionally damaged repos, and successfully
    repaired them all.
  * Allow use of --unused in bare repository.
